Help with a 130 on an OMC SeaDrive

[emoney]

So, as you can see in the pics, the motor's original bracket is removed when it's installed on the SeaDrive Tilt unit. I'm assuming that's where I would've normally found a Model number. Where else can I look? The person I got the boat from wasn't the original owner and while the bracket is original, pretty sure there wasn't a 130 hp model in 1988, isn't that correct? It doesn't seem like a different "hood" and it's got most of the other tell-tale signs of being a 130. If so, that means someone swapped out the motor for this early 90s version, but before I get into tearing it down, I need to know the model for parts purposes. Where else can I look?
